TO SAID TEAHEN' WATER CLOSET Application filed March 9,

The invention relates to water closets of the type forming the subjectmatter of our prior Patent No. 1,419,328 issued June 13, 1922. Thedistinguishing feature of this type is that the tank holding theflushing water is integral with the bowl and consequently the water headis comparatively low. However, a high velocity is imparted to the waterdischarging from the tank to the bowl in through siphonic action,thereby effecting a thorough flushing with a practically noiselessaction. Another feature of this construction is that the water from thetank is admitted to the bowl so as to cause a whirling or centrifugalaction. This action must, however, be restricted as otherwise it woulddefeat the operation of establishing the siphon, either by too greatlyretarding the flow of water into the trap or possibly forming a vortex,admitting air into the trap to break the siphon. Thus while thecleansing of the bowl is facilitated by a strong centrifugal action,such action must be controlled to of breaking the siphon.

It is the primary object of the present invention to obtain aconstruction and method of operationwhich effectively controlscentrifugal action and insures the starting of the siphon. This we haveaccomplished by dividing the water from the tank, admitting a portioninto the bowl so as to cause a whirling action therein, and utilizinganother por. tion for forming a jet of water directed upward in theupwardly extending leg of the siphon trap. The invention thereforeconsists in the construction and method as hereinafter set forth.

In the drawings: 40 Figure 1 is a plan view of our improved closet;

Figure 2 is a longitudinal section there through; a Figure 3 is a crosssection.

Figure 4is a section on line 44 of Figure 2.

The general features of our improved construction are sim'lar to thoseof the former Patent No. 1,419,328. comprising a bowl A supported upona. pedestal B containing the the point where there is no danger ing ofthe water within the bowl further in- 1931. Serial No. 521,257.

usual siphon forming return bend B and having formed integral therewitha tank C which extends across the back and overlaps the sides of thebowl. The tank extends upward above the bowl but preferably for only ashort distance as it is only necessary to have suflicient head toestablish the siphon and any further elevation of the water level issuperfluous and does not to any appreciable extent add to the velocityattained by siphonic action. The bowl D of the tank is alsoapproximately at the level of the water seal in the bowl, this givingthe maximum capacity of flushing water and any extension of the tankbelow this level being useless. Water is conveyed from the tank to thebowl through a channel E which extends beneath the bottom D anddischarging tangentially into the bowl through an opening F thereinwhich is located below the level of the normal Water seal. The ri'm G isalso provided with an annular channel H for the admission of water usedas a rim flush.

The parts thus far described are substantially the same as in our formerpatent, and in operation the flushing is effected by lifting a flushvalve (not shown) which admits water through the channel E and apertureF into the bowl, raising the level therein sufficiently to estab sh asiphon in the return bend B. This increases the velocity of dischargefrom the tank to the bowl but without the noise which usuallyaccompanies discharge from an elevated tank while the whirlcreases itscleansing efficiency.

To insure the quick forming of the siphon we have provided an auxiliarywater discharge passage F which drops below the level of the passage Eand is directed upwardly into the upwardly extending leg of the trap B.Water is diverted into this passage F by means of a baffle J extendingupward into the passage E so that a part of the water fiowing throughthe latter passage is deflected downward and around the bend and throughan aperture F into the trap B to be directed upward as just described.This produces a jet of water ascending in the leg of the trap B so as tomore quickly establish the siphon. 100

As a consequence we obtain the maximum efliciency in cleansing the bowlthrough the whirling of the water therein with certainty that the siphonwill be quickly established and not broken untilthe water is completelydischarged from the bowl.

To provide an overflow for the tank a channel H is formed integral withthe rear wall of the tank, being open at the top and at its lower endconnected into the channel E. When the flush valve is opened there willbe a tendency for the water entering the channel E to flow in bothdirections, thereby causing a rise of water in the channel H andnossibly slopping over the top. Such an efl'ect is prevented by placingin the channel E between the same and the channel H a baflle I whichwill interfere with this back flow of water. The baffle is, however,provided with a slot I extending downward therethrough which permitsdrainage of water therethrough which otherwise would be trapped. Thusthe arrangement is one which does not interfere with the overflowfunction and prevents back flow through the channel.

As the specific fittings used for controlling the admission of Water tothe tank and the discharge therefrom form no part of the presentinvention, description and illustration of the same is omitted.

What we claim as our invention is:

1. The method of flushing siphonic bowl closets consisting inestablishing a gravity water head not greatly above the normal waterseal, discharging water from said head and dividing the water sodischarged to direct a portion thereof into the bowl and another portionto form a jet for establishing the siphon.

2. The method of flushing'siphonic bowl closets consisting inestablishing a gravity water head not greatly above the normal waterseal, discharging water from this head towards an inlet into the bowland in diverting a portion of the water discharged to form a jetfor-establishing the siphon.

3. The method of flushing siphonic bowl closets which consists inestablishing a gravity water head. not greatly above the normal waterseal, discharging water from said head with a portion directedtangentially into the 'bowl and in diverting a porbowl, a deflector insaid discharge passa and a passage for the deflected water terminatingin a jet directed upward into the siphon trap.

6. A water closet comprising a siphonic action bowl, a tank connectedtherewith for forming a comparatively low water head, a dischargepassage from said tank to said bowl, a deflector in said dischargepassage for retarding the flow of water therethrough into the bowl and'a passage for the deflected water forming an upward y directed jet intothe siphon trap.

-7. In a water closet, the combination with the bowl, a tank integraltherewith, a channel beneath the tank communicating with the bowl, anoverflow channel for the tank communicating with the channel beneath thesame, and a baflie between said over flow channel and the channelbeneath the tank for the purpose described.

8. In a water 'closet, the combination with the bowl, a tank integraltherewith, a channel beneath the tank communicating with the bowl, anoverflow channel for the tank communicating with the channel beneath thesame, and a baflle between said overflow channel and the channel beneaththe tank' for the purpose described, said baflle being provided with adrainage slot therethrough.

In testimony whereo we aflix our signatures.
